Hello there I've had a bug and it broke the progress in some chains. I don't know how to describe the problem without giving spoilers, so... SPOILER ALERT don't read further if you didn't reach the university building:
So, I finished that quest, found the car, old man is deas, open the engineering bay, the tall weird girl in the engineering workshop called me for a quest but .. exploring the buildings near the vault I entered the one with the terminal that sent me to the university the first time and it reopened the quest to search in the university. I went there, but since it's all empty the quest remains incomplete, old man Gibson is alive again and the engineering area is shut again. Is there anyway to fix it?
